By: Maria Santos. Nancy Zepeda. Introduction. . What is ion-pair . chromatography (IPC)?. T. he . addition of an ionic surfactant to a reversed-. phase Chromatography system (RPC) . in order to affect retention . Stoichiometry. !. So far. In all our reactions, we assume both reactants get used up. We assume both reactants provided are pure. We rarely see these two.. Limiting reagents. Percent Purity. Percent Yield. Biuret. &Lowery Reactions. CLS 331. Exp.no.5. Introduction. There are many methods for the determination of . the amount of . protein in a natural product.. A particular method is chosen in accordance with materials to be . Bon Appetite. Suppose you are a chef preparing . F. rench toast for a group of people. You make French toast the way you have always made it: . one egg for every three slices of bread. . You never waiver from this recipe, because the French toast will be either too soggy or too dry. There are 8 eggs and 30 slices of bread in the pantry.. Yes…it’s still stoichiometry…. Think about making grilled cheese…. To make a . decent . grilled cheese sandwich, you need two pieces of bread, 2 pieces of cheese, and 1 pat of butter. Write an equation that describes making a grilled cheese sandwich. . Concerned with identifying the identity of a substance . Or whether a specific substance is present. i.e. flame test, litmus tests. Qualitative Analysis. Determining the quantity (mass or concentration) of a specific substance present in a sample. . Consider the balanced equation for the production of ammonia:. N. 2. . 3. H. 2. .  . 2. NH. 3 . If you have 2 moles of nitrogen and 3 moles of hydrogen, which reactant will be used up?. How much ammonia will you be able to make?. During a chemical reaction, the amount of each reactant will determine how much product is formed.. The . limiting reagent. is the reactant that is . used up first . in the reaction, thus determining when the reaction stops..
